The measurements have to be carried out in compli-

For all tests (measurements) follow the safety references as
described in paragraph 2.0.
Direct the measurement microphone towards the
sound emitting source.
To minimise operator influence on the measurements
make sure that the sound level meter is placed at a dis-
tance of approx. 50 cm away from the body or mount-
ed onto a tripod. The operator body acts as a sound re-
flector and can lead to an error of measurement of up
to ± 6dB.
